Comments P.208 right column 3rd paragraph: "Table 1 shows the phenotypic values and quantitative genetic parameters for egg size and number and body mass for parental and RILs [recombinant inbred lines] in C. elegans at 12°C and 24°C. Egg number in strain N2 was significantly higher at 12°C than at 24°C (t-test, P=0.003) while there was no difference in egg number in CB4856 between these temperatures. With regard to egg size, the parental strains response was significantly different. Egg sizes from CB4856 decreased with 21.3% in size in response to higher temperatures while N2 egg sizes decreased only with 8.3% analysis of variance (ANOVA, pGxE<0.001, pE<0.001). With regard to body mass parental strains responded differently to the environment (ANOVA, significant effect of temperature, P=0.04). N2 grew larger at 12°C than CB4856. At both temperatures N2 worms were significantly bigger than CB4856 individuals (ANOVA, significant effect of strain at P<0.001)." Assumed egg was a sphere, Value in parentheses is heritability
